Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an electric float used for fishing in dark fishing spots such as at night, and in particular uses a light source in which a marker member protruding from the water surface is housed in the float body. This invention relates to the improvement of an electric float of a luminescent type.

[Conventional technology]

Conventionally, this type of electric float was manufactured in the 1970s.
As shown in No. 11187 and Utility Model Application No. 56-21793,
A rod-shaped indicator member made of a light guide material such as acrylic or glass is connected to the upper end of the float body in a protruding state, and light from a light source built into the float body enters the indicator member from the end, and this incident light is It has been proposed that the light is emitted from the distal end surface of the marker member, the coating layer (cladding layer) of the marker member, or a cut portion in which the outer periphery of the core including the coating layer is partially removed to emit light.

[Problem that the invention attempts to solve]

However, when the coating layer of the sign member is removed, the amount of light emitted from the removed portion is small.
The brightness of the removed portion is low, which makes it difficult to visually recognize the presence of the marker member and, by extension, the float, and also makes it difficult to determine whether the behavior of the float is caused by waves, wind, or fish.

In addition, if a cut portion is formed deep enough to reach the light guide core that constitutes the sign member, the brightness of the cut portion can be increased compared to the method in which the coating layer is removed, but the light guide core Forming a cut with a depth of They were concentrated on the base side where they connect to the main body, and there was a risk of them being easily broken.

[Purpose of invention]

The present invention solves the above-mentioned conventional drawbacks by filling the bright part of the sign member with a translucent material,
An object of the present invention is to provide an electric float that can improve the mechanical strength of a sign member.

[Means for Solving the Problems] The electric float according to the present invention includes a float body having a built-in power source and a light source, and a marker member attached to the upper end of the float body and illuminated by incident light from the light source. In this case, the above-mentioned indicator member is composed of a light guide material having a core having a desired diameter and a cladding layer covering the outer periphery of the core, and a ring-shaped ring is formed on the outer peripheral surface of the light guide material at a depth that reaches the core. A bright part is formed by cutting, and the bright part is filled with a translucent material.

[Effect of invention]

In the present invention, when the light source is turned on and the light travels toward the upper end through total reflection within the light guiding material of the sign member, a part of the light is emitted outward from the bright part. be illuminated.

In addition, in the present invention, since the luminous part is filled with a translucent material, it has the same mechanical strength as other parts without the luminous part, and can withstand the bending force applied to the sign member. Bend accordingly.

[Example of idea]

Hereinafter, embodiments of the present invention will be described based on the drawings.

1 and 2 show an example of an electric float according to the present invention. Reference numeral 1 indicates a hollow float body, and the upper end of the float body 1 is covered with a cladding layer on the surface of a core 2a made of acrylic or glass. Rod-shaped sign member 3 made of a light guiding material with a diameter of 1 to 3 mm covered with 2b
are connected together with their axes aligned, and a light source 4 such as a light emitting diode built into the float body 1 is opposed to the inner end surface of the float body 1 of the indicator member 3, thereby allowing light from the light source 4 to be The light enters the marker member 3 from the end face.

Further, the above-mentioned sign member 3 has a luminous part 5 formed by cutting a ring-shaped notch deep enough to reach the core 2a on the outer circumferential surface of the light guiding material 2, and this luminous part 5 is a marking part. A plurality of them are formed in the longitudinal direction of the member 3, and a tip 3a is formed inside the marker member 3.
A part of the light L traveling in the direction due to total reflection is emitted outward to produce a bright light, and the bright part 5 is coated with, for example, epoxy-based, urethane-based paint, adhesive, or resin. The reinforcing layer 5a is formed by filling a material with good translucency such as
This supplements the mechanical strength of the bright part 5.

In the electric float configured in this way, when the light source 4 is turned on, when the light travels in the light guiding material 2 of the sign member 3 toward the upper end by total reflection, the light L is emitted from the bright part 5. A part of the light is emitted outward, resulting in bright light. Note that since the reinforcing layer 5a provided in the bright part 5 is made of a material with good translucency, the brightness of the light emitted from the bright part 5 is similar to that of an electric float having a conventional structure.

[Effect of idea]

As described above, the present invention forms a luminous part by cutting the outer peripheral surface of the indicator member attached to the upper end of the electric float into a ring shape with a depth that reaches the core, and at the same time, the luminous part is made of a translucent material. The floats are easily visible and the fish are easy to identify, and the luminous part has the same mechanical strength as other parts without a luminous part. If force is applied to the luminous part to cause breakage, such as if the sign member is carelessly bent when installing the electric float, or if the electric float collides with a rock, structure, etc. during fishing. There is no risk of breakage from the bright part.
